CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 302,442, dated July 22,1884.

Application filed July 25, 1883. (No model.)

To LUZ whom it may concern:

Be it known that I, WILLIAM CYRUS STRONG, of Readfield, in the county ofKennebec and State of Maine, have invented a new and ImprovedGarburetor, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a simple, cheap, and safemachine for the generation of gases from gasoline or other volatileliquids and air, the apparatus being specially adapted for furnishingheating-gases for jewelers, dentists, chemists, tinmen, and othersrequiring a constant or occasional heatingflame, as from a Bunsen orother burner, which may be connected with the apparatus, which is moreespecially intended tobe of a portable character, but which may vary insize and capacity, as required.

The invention consists in a novel construction of the air-trap to thebell, to be opened self-actingly by the lifting of the bell; also, in

the apparatus, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a vertical central sectional elevation of a gas-machineembodying my improvements. Fig. 2 is a sectional plan View of thecarburetor 011 the line w m, Fig. 1, with the gas-trap removed; and Fig.3 is a vertical section of the air-trap of the bell on an enlargedscale.

The letter a represents a tank, open at the top to receive theopen-bottomed bell b, which is fitted and guided in any approved Way toslide within the tank a and outside of the gasoline receptacle or vessel0 and carburetor d, which'latter receives its air-supply through thestand-pipe e and trap f direct from the bell b, to which bell air issupplied at intervals, as required, through the air-trap g, which is arranged to open automatically by the lifting of the bell by the ring orother handle h of the air-trap. This trap g is constructed with a plate,'5, preferably of circular form, and having a downwardly projectingflange, j, which is seated upon a suitable packing, k, in the bottom ofan annular recess, Z, in a centrally-apertured cap-plate, m, fixed tothe head of the bell b, the recess Z above the packing it beingpreferably filled with a liquid-such as glycerine-in which flange j iscentrally held, thereby making either a solid or liquid packing, orboth, to effectually prevent the escape of air from the bell I) throughthe trap g. The plate 13 of the trap, to whiclrhandle h is fixed, alsocarries one or more (preferably two) rigid rods or bars at, at the lowerends of which the apertured bell-lifting bar or plate 0 is suitablyheld, the rods a passing through lugs or a flange of the cap-plate m fora guide, and also carrying springs p, which act between plates m and 0,to promptly seat the flange j on the packing is and close the air-trapwhen released. Then the air-trap is opened by the weight of the bell b,said bell being lifted by the handle h, the springs 19 are compresseduntil plate 0 meets the head of the bell b, for lifting it without unduestrain on the springs. The plate 0 may also serve as a weight forclosing the trap g, and the springs p be dispensed with, if desired.

The letter q represents a tube which passes through the gasoline-vesselc and carburetor (1, preferably through their center, as shown. Thistubeq extends to the bottom of tank a, to which it isfixed. with anysuitableair and water tight joint, thereby holding the vessel 0 andcarburetor d in proper relative position with the tank a and slidingbell b, and affording space to receive the trap f into which the pipe 6extends to near the bottom, and in which the air-outlet r, for supplyingair to the carburetor through the opening sin the side of tube isplaced.

The trap f is filled with liquid to a sufficient distance above the openlower end of pipe 0, or about to the dotted line i, to seal the pipe 0and bell 1) against back-flow of gases from the cap, '0, for the tube (1is fitted air.and water tight to the gasoline-vessel c, and serves as astay to laterally support and stiffen the tube e, which is or may besoldered into the cap. The gasoline-vessel c is charged with thevolatile fluid through an opening closed by a plug, 10, and dischargesthe fluid to the carburetor (I through a pipe or tube, w,which opensfrom the bottom of vessel c,and extends down into the carburetor to apoint corresponding to or a little below the desired level of thevolatile fluid in the carburetor, which level is indicated by the dottedline 3 in Fig. 1.

I make the carburetor d in a manner to compel a circuitous route thereinor therethrough of the air from the bell I) and the volatilized productsof the liquid fed from vessel c, a preferred construction being shown inthe drawings, which represent,in Figs. 1 and 2, a spiral partition,a,which is close-j ointed at Z) to the flue or tube g, and windsoutwardly to the outer wall of the carburetor, to which it isclose-jointed at a, so that the air entering the carburetor at s fromtrap fwill follow the course of the spiral partition to the outletpipe(1, meanwhile mingling intimately with the volatilized products from thegasoline or other suitable liquid fed from the vessel 0 through the tubeor pipe x. The partition to makes a close joint at the top with the headof the carburetor d, which head in this example also serves for thebottom of the gasoline- ,vessel 0, while the lower edge of the partitiona is free from the bottom plate, a, of the carburetor to afford a freercirculation of the volatile liquid within the carburetor, which isfilled with any suitable fibrous substance in the usual or any approvedmanner.

The outlet-pipe d for the generated gas is bent upon itself at the top,as at (1 its mouth facing downward to avoid excessive inflow of thevolatile liquid to the pipe should the ma chine be tipped sidewise orviolently jarred in handling it; and any'suitable drip-plug, f, isfitted to the pipe 01, which has also a valve or stop-cock, g, tocontrol the discharge of gas from the machine to any connected pipe or-burner for use, as required.' This pipe (1,

from its head d-,passes downward through the carburetor and itsbottom-plate e, and through the water in the space a of tank a below thecarburetor, said pipe (1 bending outward and passing through the wall oftank a near its bottom, and then upward or in any convenient directionto the point of discharge. YVater is filled into the tank a up to aboutthe line h, Fig. 1, thus entirely surrounding the gasoline vessel 0,carburetor d, and the lower bend of the gas-discharge pipe (2, therebyefficiently water-jacketing these parts containing the inflammableliquids and gases and making the machine safe against explosion. A plug,t",

in the tank a permits discharge of the water therefrom for a freshsupply, when desired.

The operation of my apparatus is as follows: The parts being in thepositions of Fig. l, and the bell b removed from the tank a, thegasoline or other volatile fluid is fed into the vessel c at w up toabout the line 7t, and the opening at w closed, the valve g beingpreviously closed. The gasoline descends into the carburetor (Z up toabout the line The trap f is suitably charged with the sealing'-fluid.The tank (a is next charged with water,which freely circulates about thevessel 0 and carburetor d, as indicated by the arrows Z. The bell I) isthen placed in the tank a, and incloses a body of air, which is forcedby the compression of the weight of the bell through the pipe 0, trap f,and carburetor d, where it meets and mingles with the volatilizedgasoline, the course of the air and mixed air and volatilized fluidbeing indicated by the arrows m, and upon opening the valve gthe gasgenerated escapes from pipe d to the burner. The bell b descends in thetank a by the outflow of the air therefrom to the carburetor, and whenthe bell has reached the limit of its downward movement it is raised bylifting on the handle h, which automatically opens air-trap g and admitsa fresh supply of air to the bell, which is lifted to proper height andreleased,whereupon trap g closes air-tight sclf-aetingly and the feed ofair to the curburetor proceeds as before, the action of the machinebeing practically continuous as long as desired while the fluid supplyin vessel 0 lasts.

The bell and tank may be fitted with any suitable stop devices to limitthe up and down movements of the bell, which may also have an alarmattachment of any approved kind, for indicating its stop at the lowestpoint, that it may be promptly raised to maintain the air supply.

To stop the action of .the machine, the bell may be lowered while thetrap g is held open for free escape of air,

The cap 1) may be removed with trap f, for examination or repairs whenrequired,

It is evident that the carburetor (Z may be made in various ways for acircuitous travel of the air and gases through itas, for in stance, aseries of zigzag partitions may sub- .stitute the spiral partitions a,and the pipes c and trap f may be located at the side of the machine orotherwise away from its center; and the gasoline-vessel c and carburetord may be arranged with awater-circulating space between them, ifdesired; and the details of construction may otherwise vary within thescope of my invention.

All the parts of my machine may readily be reached for adjustment andrepairs, the construction in the first instance being ineX- pensive; andthe product of the machine is a gas rich in calorie and well adapted forits intended uses.

I do not abandon or dedicate to the public any patentable feature setforth herein and not hereinafter claimed, but reserve the right to claimthe same either in a reissue of any patent that may be granted upon thisapplication or in other applications for Letters latcut that I may make.
